MICROCONTROLLERS POWER SUPPLY

Any microcontroller needs a powersupply to work,the supply must give constant
a constant output voltage.for all our microcontrollers we need a 5V supply.her
e is a simple circuit which gives a regulated supply voltage.and we constantly
use this in our every microcontroller project.

EXTRA READING:
1.prefer to use 1Amp trasformer,as many can be connected to the single supply.
2.you can also half wave rectifier instead of a bridge rectifier,just modify
the rectification section.
3.a 7805 ic used here gives out a constant supply of 5V
4.the capacitors used there are for smoothening and
avoiding unwanted ripple.
